Brass Flat Seat Union M/F EPDM
Flat-seat union fitting M/F in brass with integrated EPDM gasket, providing a dismountable connection point between a female and a male element. Ideal mixed configuration for equipment connections. Standard ISO 228-1 BSPP.
Description of the Flat-Seat Union Fitting M/F in Brass
This mixed M/F union consists of three parts: a male body, a female body and a swivel nut. The integrated EPDM gasket ensures the sealing of the flat junction. It creates a quick disconnection point in the circuit.
The M/F configuration is particularly useful for direct connection to appliances or valves that already have a male or female thread. Disassembly and reassembly possible without affecting the rest of the installation.
